$30 - $60 USD
Provenance History

Art Historical Significance
A modern continuation of a 17th-century English seafaring tradition. While aesthetically pleasing, its primary value is decorative rather than museum-tier fine art, representing the democratization of the studio glass movement.
Notable Features
Distinctive cobalt blue trailing and an organic, slightly asymmetrical form that confirms its hand-blown, non-mold origin.
Condition Issues
Visible surface dust and minor scuffing typical of shelf wear. The rough pontil at the 'stem' is a manufacturing artifact, not damage.
Conservation Recommendations
Regular cleaning with a soft, lint-free cloth and mild soap. Avoid extreme temperature changes to prevent thermal shock/cracking.
